FWIW both Thunderbird and Mail use the mbox format to there's no need to do any conversion. You may be able to just point them both at the same folders, not sure.
The reason I ditched Thunderbird on the Mac was its complete inability to make any sense whatsoever of stuff pasted from another application. A simple table (like an itin) copied from Firefox becomes two pages of randomly-formatted-and-aligned garbage when pasted into Thunderbird.
